Astronomers discover giant relic of disrupted 'tadpole' galaxySource: American Friends of Tel Aviv UniversityA team of astronomers from Israel, the United States and Russia have identified a disrupted galaxy resembling a giant tadpole, complete with an elliptical head and a long, straight tail, about 300 million light years away from Earth. The galaxy is 1 million light-years long from end to end, 10 times longer than the Milky Way.

"We have found a giant, exceptional relic of a disrupted galaxy," says Dr. Noah Brosch of The Florence and George Wise Observatory at Tel Aviv University's School of Physics and Astronomy, who led the research for the study.

When galaxies are disrupted and disappear, their stars are either incorporated into more massive galaxies or are ejected into intergalactic space. "What makes this object extraordinary is that the tail alone is almost 500,000 light-years long," says Prof. R. Michael Rich of UCLA. "If it were at the distance of the Andromeda galaxy, which is about 2.5 million light-years from Earth, it would reach a fifth of the way to our own Milky Way."

Drs. Brosch and Rich collaborated on the study with Dr. Alexandr Mosenkov of St. Petersburg University and Dr. Shuki Koriski of TAU's Florence and George Wise Observatory and School of Physics and Astronomy. The results were published in the Monthly Notices of the Royal Astronomical Society.

According to the study, the giant "tadpole" was produced by the disruption of a small, previously invisible dwarf galaxy containing mostly stars. When the gravitational force of two visible galaxies pulled on stars in this vulnerable galaxy, the stars closer to the pair formed the "head" of the tadpole. Stars lingering in the victim galaxy formed the "tail."

"The extragalactic tadpole contains a system of two very close 'normal' disk galaxies, each about 40,000 light-years across," says Dr. Brosch. "Together with other nearby galaxies, the galaxies form a compact group." The galaxy is part of a small group of galaxies called HCG098 that will merge into a single galaxy in the next billion years.

Such compact galaxy groups were identified in 1982 by astronomer Paul Hickson, who published a catalogue of 100 such groups. The Hickson Compact Groups examine environments with high galaxy densities that are not at the core of a "cluster" of galaxies (clusters contain thousands of galaxies themselves). The "tadpole galaxy" is listed as No. 98 in the Hickson Compact Group catalogue.

"In compact group environments, we believe we can study 'clean' examples of galaxy-galaxy interactions, learn how matter is transferred between the members, and how newly accreted matter can modify and influence galaxy growth and development," says Dr. Brosch.

For the research, the scientists collected dozens of images of the targets, each exposed through a wide filter that selects red light while virtually eliminating extraneous light pollution. "We used a relatively small, 70-cm telescope at the Wise Observatory and an identical telescope in UCLA, both of which were equipped with state-of-the-art CCD cameras," says Dr. Brosch. The two telescopes are collaborating on a project called the Halos and Environments of Nearby Galaxies Survey.

The new study is part of a long-term project at TAU's Florence and George Wise Observatory, which explores the skies at low light levels to detect the faintest details of studied galaxies.

Virtual reality simulation of a supermassive black holeSource: BioMed CentralThe black hole at the centre of our galaxy, Sagittarius A*, has been visualised in virtual reality for the first time. The details are described in an article published in the open access journal Computational Astrophysics and Cosmology.

Scientists at Radboud University, The Netherlands and Goethe University, Germany used recent astrophysical models of Sagittarius A* to create a series of images that were then put together to create a 360 degree virtual reality simulation of the black hole, that can be viewed on widely available VR consoles. The authors suggest that this virtual reality simulation could be useful for studying black holes.

Jordy Davelaar, corresponding author, said: "Our virtual reality simulation creates one of the most realistic views of the direct surroundings of the black hole and will help us to learn more about how black holes behave. Travelling to a black hole in our lifetime is impossible, so immersive visualizations like this can help us understand more about these systems from where we are."

The authors also suggest that the virtual reality simulation could help encourage the general public, including children, to take an interest in astrophysics.

Davelaar said: "The visualisations that we produced have a great potential for outreach. We used them to introduce children to the phenomenon of black holes, and they really learned something from it. This suggests that immersive virtual reality visualizations are a great tool to show our work to a broader audience, even when it involves very complicated systems like black holes."

Heino Falcke, Professor at Radboud University adds: "We all have a picture in our head of how black holes supposedly look, but science has progressed and we can now make much more accurate renderings -- and these black holes look quite different from what we are used to. These new visualisations are just the start, more to come in the future."
